Web1. : the twisting or wrenching of a body by the exertion of forces tending to turn one end or part about a longitudinal axis while the other is held fast or turned in the opposite direction. also : the state of being twisted. 2. : the twisting of a bodily organ or part on its own axis. 3.

WebIn the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the pascal, an SI unit for newtons per square metre, or in pounds per square inch while torque is expressed in newton metres or foot-pound force. In sections perpendicular to the torque axis, the resultant shear stress in this section is …

WebTorque is a moment that twists a structure. Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section. To keep things simple, we're going to focus on structures with a circular cross section, often called rods or shafts.

WebFeb 24, 2022 · Testicular torsion occurs when a testicle rotates, twisting the spermatic cord that brings blood to the scrotum. The reduced blood flow causes sudden and often severe pain and swelling. Testicular torsion is most common between ages 12 and 18, but it can occur at any age, even before birth. Testicular torsion usually requires emergency surgery.

Webtor·sion ( tōr'shŭn ), 1. A twisting or rotation of a part on its long axis or on its mesentery; often associated with compromise of the blood supply. See also: intorsion, extorsion, dextrotorsion, levotorsion. 2. Twisting of the cut end of an artery to arrest hemorrhage. See also: intorsion, extorsion, dextrotorsion, levotorsion. 3.

WebJul 6, 2022 · The term torsion refers to the act of twisting an object (or structural member) due to applied torque (that is, a type of force resulting in the object rotating around an axis). In physics ...

WebJan 11, 2023 · The torsion can be defined by (1) where is the unit normal vector and is the unit binormal vector. Written explicitly in terms of a parameterized vector function , (2) (3) (Gray 1997, p. 192), where denotes a scalar triple product and is the radius of curvature . The quantity is called the radius of torsion and is denoted or . See also

WebFeb 24, 2022 · Testicular torsion can occur in newborns and infants, though it's rare. The infant's testicle might be hard, swollen or a darker color. Ultrasound might not detect reduced blood flow to the infant's scrotum, so surgery might be needed to confirm testicular torsion. Treatment for testicular torsion in infants is controversial.

WebTorsion is a rare but very serious condition. It affects about one in 4,000 males under the age of 25. It is most common in adolescents between the ages of 12 and 18, a group that accounts for 65 percent of all cases. It can affect newborns within the first year of life. This condition can also affect men over 25, although that is rare.

WebTorsion (algebra) In mathematics, specifically in ring theory, a torsion element is an element of a module that yields zero when multiplied by some non-zero-divisor of the ring. The torsion submodule of a module is the submodule formed by the torsion elements. A torsion module is a module that equals its torsion submodule.
